Are you looking for a handgun scope, or open to shooting a rifle scope on it? I run rifle scopes on most of my specialty pistols, which opens up a lot of doors for availability and options.
For a handgun scope, the Burris 3-12x is the only higher magnification model, AND the only Adjustable Objective model I'm aware of, both features being big advantages for specialty pistols. The extreme downsides to this scope, however, are the reticle available (a drop compensator), and the incredibly low 28MOA internal adjustment. But given a 20moa base, 28moa will get you quite a ways out there. The Leupold VX3 2-8x is another common option as a handgun scope, but it's a fixed parallax model. I use these on a handful of revolvers, for 200-300yrd shooting, they're very serviceable.
If you're open to a rifle scope, then I'm a buy once, cry once guy. I have a Sig Tango4 4-16x44 with a milling reticle on one of my XP100's in 221FB, and I'm looking to put another one on a Savage Striker 243win. Right now, the Savage is wearing a CHEAP Bushnell Trophy Extreme 4-16x44mm, which is serviceable, but is only a plex reticle, SFP, and is uber cheap... I have a NF SHV 4-14x50 F1 on a custom 700 Specialty pistol as well in 284win. I have a CHEAP Nikon Buckmaster (discontinued, but they're around) 6-18x40mm Mil-dot (midway exclusive) Side Focus on a Ruger Charger which is very serviceable as a rifle scope on a specialty pistol.
If you're stuck on a Leupold, then the Leupold VX3i 4.5-14x50mm with mil dot or TMR reticles are my go-to hunting "budget friendly" scopes. These are obviously rifle scopes, but I had one on that 284win for a while before I swapped it for the NF SHV F1, and have a half dozen others on other rifles. Very good optics.
So for a Leupold, I'd personally use the VX3i 4.5-14x50mm with a mildot or TMR, OR if you want a handgun scope with longer eye relief, the VX3 2-8x32mm, and send it in for a mil-dot reticle.
